PURPOSE:To save labor for adjusting air pressure in a tire according to traveling speed of an automobile by mounting weight on a tube or wheel. CONSTITUTION:Weights 1 are mounted on the wheel 3 side of a tube 2 by suitable methods such as adhesion, embedding, etc. Thus, the weights 1 are moved outward by centrifugal force during traveling to reduce the volume of air enclosed in the tube 2 and heighten air pressure in the tube 2. Hence, by selecting suitably the weight, shape and quantity of the weights 1, desired variation of the air pressure can be obtained for desired range of traveling speed to dispense with adjustment of the air pressure in the tire according to the traveling speed. |
